@Mother2Hens, I learned the hard way several years ago that chickens LOVE Styrofoam! We have Styrofoam insulation on a few doors to roots in our main coop, and quickly discovered their proclivity for it. Fortunately none became ill, but treated foam could certainly cause illness. The pipe stuff no doubt has additives to make it hold its shape and make it less brittle. Crazy chickens, once they explore a substance and find Styrofoam, they really go after it and it must be removed.
I sure hope Frieda makes a full revovery! How are your chocolate and chocolate cuckoo Orps? The cuckoo girl I kept is such a doll. I purchased a new chocolate cuckoo cockerel from Papa's in California to replace my mean roo of last year, but none of his female offspring have been afflicted with his attitude. The new boy is almost as beautiful but very mellow. I have a pen with 5 birds for my chocolate and cuckoo breedings, and will do some pair breeding with my blue girls to get some mauves as well.
My SGDs have started to lay! They are very easy going and sweet now that they are at POL. The pullets are their adult color, but not the cockerel yet. Probably next year.
Cogburn still reigns over the layer flock, Roadrunner from @jchny2000 over the lavenders, and Junior (Cogburn's son) over the blues. My cockerels need names (SGD and chocolate cuckoo Orp).
Our layers are aging, so we have 15 black Australorp pullets in the garage! I know there are hybrid layers that are super layers, but they burn out young and/or have more medical issues. Our original Australorps laid 5-6 eggs per week when young, and were hardy. I'd rather have heritage breeds most of the time for that reason.
